struts 2.3.28+spring 4.2.5.RELEASE+hibernate 5.1.0.Final整合maven构建项目基本配置

第一次写博客，主要也是记录给自己看的，可能很多比较熟的地方就没注释

用maven构建，ssh框架都是选用的最新的release版（感觉还是不要用beta），环境jdk1.8 tomcat8.0 mysql5.7.11

maven配置

所有的框架我都是从core、context包开始配，缺啥配啥，基本web项目通过spring aop进行事务管理就应该是这样了。PS：maven不得不说加包好方便第一次用就爱上了。

struts2-spring-plugin包要注意<exclusions><exclusion>配置排除 不然会自动添加spring低版本的包（好像3.X.X）。

然后我是加了server runtime的library，不加的话需要配置servlet、jsp相关包。

如果是eclipse的目录结构，则要在</dependencies></project>之间加入

  <build>

    <sourceDirectory>src</sourceDirectory>

    <plugins>

      <plugin>

        <artifactId>maven-compiler-plugin</artifactId>

        <version>3.3</version>

        <configuration>

          <source>1.8</source>

          <target>1.8</target>

        </configuration>

      </plugin>

      <plugin>

        <artifactId>maven-war-plugin</artifactId>

        <version>2.6</version>

        <configuration>

          <warSourceDirectory>WebContent</warSourceDirectory>

          <failOnMissingWebXml>false</failOnMissingWebXml>

        </configuration>

      </plugin>

    </plugins>

  </build>

PreferencesPlaceholderConfigurer读取jdbc.properties配置文件

sessionFactory是hibernate的核心，并需要配置dataSource

　　hibernate映射用的是注解（无需映射配置文件）

hibernateTemplate是spring为hibernate提供的持久化操作模板，可以简化Dao中的数据库操作，配置自动装载sessionFactory

　　###如果Dao类是extends HibernateDaoSupport的，则无需多配置hibernateTemplate，只需注入sessionFactory便会自动创建一个hibernateTemplate###

　　可以参见HibernateDaoSupport的源码

    /**

     * Set the Hibernate SessionFactory to be used by this DAO.

     * Will automatically create a HibernateTemplate for the given SessionFactory.

     * @see #createHibernateTemplate

     * @see #setHibernateTemplate

     */

    public final void setSessionFactory(SessionFactory sessionFactory) {

        if (this.hibernateTemplate == null || sessionFactory != this.hibernateTemplate.getSessionFactory()) {

            this.hibernateTemplate = createHibernateTemplate(sessionFactory);

        }

    }

txManager是spring为hibernate提供的事务管理类，配置自动装载sessionFactory

<tx:advice>下配置事务属性

<aop:config>配置切入点

web容器中需要容器获取配置，需要在web.XML中配置ContextLoaderListener，并指定xml位置

struts2配置

struts.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

    <package name="any" namespace="/">

        <action name="x" class="action.TestAction">

            <result>/index.jsp</result>

        </action>

    </package>

</struts>

随便写的个测试的，和单独的struts配置一样

也要在web.xml中配置StrutsPrepareAndExecuteFilter

加入struts2-spring-plugin包之后无需在applicationContext.xml中配置action的bean，但需要注解注入service。

服务器启动时会读取包中struts-plugin.xml

web容器配置

StrutsPrepareAndExecuteFilter在struts2.1.3之后官方推荐使用，之前是FilterDispatcher
